BED-BOTTOM on THE LIKE.

To all who/2t it may concern 7 v Be it known that ITBURTNETT McIn'rosrI, ;1. (.1lt1Zel1Of the United States, residing at Brooklyn, in the county of Kings and State ofTNew York, have inventedcertain new and useful Improvements in Bed-Bottoms or-the like, of which thefollowing is a specificahis invention relates to a support and particularly useful when employed as a support 111 hospitals for the mattress wounded under circumstances when it is necessary to positively. or rigidly. support the patients body at all points, that is in such a way as will not permit any downward yielding movement such as is possible with bedsprings as usually constructed.

Among the objects of my invention is to provide a support of very simple construction which can be made quite rigid throughout and which would operate to support a mattress unyieldinglyl as suggested above. lfprovide supportingmeans 'to extend un- .der the mattress and provide simple means for, placing the supporting means in ten- .sion to render it rigid.

1 In the drawing. Figure 1 is a plan of a mattress support embodying my invention and showing the samebefore the parts are brought into their final relation of rigidity; Fig. 2 is. a plan ofra mattress support shown in Fig. 1 but with the parts in their final state of rigidity; Fig. 3 is a detail and is a.

These members are preferably in the form of relatively thin flat strips popularly called strap iron and they are preferably woven together to produce a wide mesh such as illusprefer to provide pair 'ofoppositely disposed resilient bars 3,3 which are preferably formed original lyas slightly bowedjbars, see lFi 1. dlSPOSGflVlthwtl'lGll' concave sides toward thewoven members 1 and 2.

simply adjustin crews a clamped to the ends of the longitudinal straps 1 and passing loosely through the bowed bars to receive nuts 5, whichwhen tightened up will evidently flex the bowed bars toward a substantially straight line, see Fig. 2, and thereby cause the bowed bars to exert tension in the members 1. I

I provide means for developing tension in the supporting means inanother or transverse direction. In order to accomplish this I prefer to provideside bars 6, 6 which are attached to the ends of the bars 3, 3 and also attached at a plurality ofpoints to the sup porting means. In the present embodiment the ends of the transverse members 2 are attached to the bars 6. a When the bars 3,3 are flexed (by tightening the nuts 5) toward a substantially straight line, the effective length of the bars 3. 3' increases, and'this of course exerts a Sion in the members 2, I prefer to provide 1 means for counteracting this effect, and at the same. time to assist in exerting tension in themembers 2. For this purpose I prefer to provide inclincd struts or diagonal braces 7 at the corners, which connect intermediate points of the bars 3 and 6. When the bowed bars 3 straighten out or approach their straight condition, the struts 7 exert an outward thrust and cause a slight outward movement orspreading movementv of the middle portions of the side bars 6. Hence the diagonals perform a double function of preventing an inward movement of the sides 6' and actually produce an outward movement of the sides. y

i It is understood tha the embodiment of the invention described above is only one of the many forms or embodiments the invention may take and I do not wish to be limited in the, practice of my invention nor in myelaims to the particular embodiment Set forth.

I claim':

A mattress support com-prising suns side bars attached to said supporting means,

a bowed bar, a connection between the bowed bars and the side bars, and means connecting said bowed bar and said supporting means at a plurality of points for flexing said bar toward a substantially straight form and thereby developingtension in said supporting means. 2. A mattress support comprising supporting means to extend under the mattress, side bars attached to said supporting means, a resilient bowed bar, a connection'between the bowed bar and the side bars, means connecting said bowed bar and said supporting means at a plurality of points for flexing said bar toward a substantially straight form and thereby developing tension in said supporting means.

3. A mattresssupport comprising supporting means to extend under the mattress,

side bars, means connecting said bowed bar and said supporting means at a plurality of points for flexing said bar toward a sub stantially straightform and thereby devel oping tension in said supporting means.

4. A "mattress support comprising supporting means to extend under the mattress, a resilient bowed bar, means connecting said bar and said supporting means at a plurality of points on said bar, for flexing said bar toward a substantially straight form and thereby developing tension in said sup porting means in 'one'direction, and means for imparting force from said bar to said supporting means transversely to exert tension in said supporting means in another direction.

5. A mattress. support comprising supporting means to extend under the mattress, bowed resilient bars, means connecting said barsand said supporting means at a plurality of points on said bar for flexing said bars towarda substantially straight form and developing tension in said supporting means in one direction, side bars attached to said supporting means at a plurality of points, and attached to said resilient bars to receive spreading force from said resilient bars to impart tensionto said supporting means in another direction. 7

r 6. A mattress support consisting of sup porting means to extend under the mattress, sidebars attached to said supporting means, a pair of oppositely disposed bowed bars, a connection between the bowed bars and the side bars, and means connecting said bowed bars and supporting means at a plurality of points for flexing said bars towarda subcapres arms patent may e obtained for stantially straight form and thereby exerting tension in said supporting means.

7. A mattress support consisting of supporting means to extend under the mattress,

means, connecting said bars and said sup porting means at aplurality of points along said bars for flexing said bars toward a substantially straight form and exerting tension in said supporting means, side bars attached to said supporting means, and inclined struts connecting said bowed bars and said side bars for im'parting force from said bowed bars to said side bars to exert tension transversely in said supporting means.

' 8. A mattress support consisting of supporting means to'extend under the mattress consisting of a plurality of longitudinal and transverse members, a pair of oppositely disposed bowed bars, means connecting said bars and said supporting means at a plurality of points along said bars for flexing said bars toward a substantially straight form and exerting tension in said supporting means, side bars attached to said supporting means, and inclined struts connecting said bowed bars and said side bars for imparting force from said bowed bars to said side bars to exert tension transversely in said supporting means.

9. A mattress supportconsisting of a plurality of longitudinal and transverse members, a pair or oppositely disposed'resilien t bowed bars, side bars abutting againstthe ends of the bowed bars and connected to the transverse members, means connecting said bowed bars and said longitudinal members at a plurality of points on said bowedbars for flexing said bowed bars toward a substantially straight form and exerting tension in said longitudinal members, and imparting a spreading force from said bowed bars to exert tension said transverse members.

10. A mattress support consisting of a plurality of longitudinal and transverse members, a pair of oppositely'disposed resilient bowed bars, tension devices connecting said'longitudinal bars respectively-with said bowed bars at a plurality of points on I said bowed bars to said side bars and there by exert tension in said transverse members, In testimony whereof I aflix my signature in presence of two witnesses. v
